Restoring BT Mobile Voicemail on OnePlus
Call 1571 from your BT Mobile SIM. If the call connects and asks for a PIN, voicemail is working but the divert may need restoring. If the call fails, proceed to the next step.
Dial **61*1571*11*30# from your OnePlus phone dialler and press Call. This re-enables the voicemail divert for unanswered calls on BT Mobile.
Dial **67*1571*11*30# (busy) and **62*1571*11*30# (phone off/no signal). This restores voicemail when your OnePlus is unavailable on BT Mobile.
If voicemail asks for a PIN you do not know, call 0800 800 150 to reset it. BT Mobile will verify your identity before resetting the voicemail PIN on your account.
The BT Mobile app or Visual Voicemail feature on your OnePlus may give direct access to messages without a PIN. Check your BT Mobile app for a voicemail or messages tab.
If using codes, ensure the voicemail number is in full UK format. Some OnePlus models require a + prefix: +441571 instead of 0 or just 1571.
If voicemail has never worked or was recently lost after a plan change, call 0800 800 150. BT Mobile may need to re-provision the voicemail service on your account.

How do I set up voicemail on BT Mobile?
Dial 1571 from your OnePlus and follow the recorded prompts to set your PIN and record a personal greeting. If voicemail is not set up, callers will hear a default BT Mobile greeting. You only need to do this once.
